Timo_8648432e

So I just switched from a mac to a windows desktop, and right before I got the new desktop on hand I found out when I click export I couldn't find the option of (.abc), it doesn't work when I reinstall the add on nor the whole application, but it does appear when I've reinstalled it on my windows desktop, so I just go with it, but today the option disappears again, I couldn't find the answer anywhere, anyone has experienced the same? And It will so much helpful and appreciated if anyone knows how to slove that!
